    [ https://issues.apache.org/jira/browse/HBASE-4668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13443305#comment-13443305 ] 

Jesse Yates commented on HBASE-4668:
------------------------------------

Any progress on this or should can we close as stale? It would be good to have a single place for this for things like HBASe-6055.

> There are a host of improvements that help:
> - HDFS fast copy
> - Various enhancements to fast copy to speed up things
> - File level hard links - which does ext3 hardlinks instead of copying blocks thereby saving a lot of iops
> Need to list out the HDFS jira's and have patches on them.
